There’s a HTC Leo ROM going round, since it’s been leaked on the web and its main attribute is the fact that it allows us to have a look at the future TouchFLO 3D version (Manila 2.6). You can check out this UI in the video below, running on HTC Touch Diamond2:

Last time we’ve stumbled upon info regarding the new interface, we’ve seen its initial settings, keyboard (identical to the one on Hero) and we’ve found out that HTC Leo uses a unique way to insert a SIM card. Notice how all the UI’s elements run perfectly on Touch Diamond2 and they support deep customization.

The most appealing features are the Phone Gallery and audio player, that now come with a bunch of cool 3D effects. Plus, the messaging menu has also been modified and overall the interface resembles HTC Sense, so we might be getting some widget action soon.
